cisco catos and Big IP LACP setup

Going through F5 setup with legacy catos switches and trying to setup LACP, I only couple of commands on forums and cisco docs:

        CatOSSwitch (enable) set channelprotocol lacp 2
        Mod 2 is set to LACP protocol.
        CatOSSwitch (enable) set port lacp-channel 1/1,2/1
        Port(s) 1/1,2/1 are assigned to admin key 56

But, this is not enough, 1 more step is needed for this setup to work:

This one is quite obvious but there is a catch.

All the ports in port-channel need to have same native vlan. And here is the catch, since it is 801q VLAN trunk, you can’t use a 801q VLAN as native VLAN. So as soon as you set a native vlan not part of 801q tagging, you would be able to see all interfaces in lacp trunk in Big IP.

Setting up Big-IP LTM for first time

Got the shiny new LTM Big-IP 1600 from F5. Just getting the box setup notes. Will write more as I setup the box to do the actual work.

IP setting and all can be done from the LCD menu presumably as well, I used the console connection.

Step A. Console Connection

To configure a serial terminal console for the BIG-IP system, perform the following procedure:

  1. Connect the null modem cable to the console port on the BIG-IP system.
  2. Connect the null modem cable to a serial port on the management system with the terminal emulator.
  3. Configure the serial terminal emulator settings according to the following table:
Setting Value
Bits per second [baud] 19200
Data Bits 8
Parity None
Stop Bit 1
Flow Control None
The default root password is default, and the preferred default IP address is 192.168.1.245

Step B. Configure IP settings.


After logging into console, type config

That opens up IP settings menu, easy to follow.

Step C: HTTPS access and licensing:

https://<IP&gt;

At the login prompt, type admin for the user name, and admin for the password.

The Licensing screen of the Configuration utility opens.

Network config first, give hostname, change password.

then license activations- > takes to f5 site, enter dossier….

That is it, you are ready to start configuring and load balancing.

I would most more as I work on setting this up.

Thanks for reading.
